This picture shows early music duo Michael and Doreen Muskett in January 6 1979, who were both to perform a concert organised by Blackburn Concert Society.

They were due to present a programme called Musique Champetre, French works of the court and countryside from the 12th to the 18th century.

At the concert in Wesley Hall, Feilden Street, Blackburn, they presented medieval and baroque instruments such as the harp gemshorn, recorders, harpsichord, cabrette and vielle-a-roue.

The music that was going to be played included 16th century dances by Arbeau pastourelles and musettes by Chadville.

The Musketts gave their first London concert in 1970 in the Purcell Room, the smallest of the South Bank concert halls, which suits their informal presentation admirably.

By this date they had sold around 80 concerts in the same hall and in the larger Queen Elizabeth Hall.

Their first programme, for which they were renowned, was Flutes, Reeds and Whistles, a short history of wood-wind instruments from the middle ages to the present day.

With many different instruments, their aim was to play from each period on the instruments which were in use at the time, leading to a discovery of new sounds.
